Just had a pest controller from the council out, and he’s left a couple of bait stations round the house with stuff called ‘Ratimor’ in it for a mouse problem that’s cropped up, or merely come to light over the weekend. Reading the info on this stuff he’s left, and apparently it also contains mummifying agents, so if a mouse does die somewhere, it shouldn’t produce a smell.
He’s also left me a couple of snap traps as well, as I’m not particularly squeamish about dealing with the aftermath.
